Those power numbers are really impressive. The most interesting part though is how close AMD is getting to the M1 pro. Apple's magic ARM chip, as it turns out, may just be benefiting from being on 5nm (many of us alread knew this) and I cant wait to see what zen 4 on 5nm brings to the table.
Based on the graphs, maybe? Zen 3+ is dramatically more efficient then zen 3 was, and zen 4 will be on the notably more efficient still 5nm node. In the majority of cases for laptops zen 3+ will be superior simply because most laptops cannot entertain 45 watt power draw today, let alone 75 watt.
Getting a i5 or ryzen 5 means getting a slower and weaker iGPU. Did you not think that someone buying this for the iGPU might, well, want the iGPU?
Shocking, I know, but not all of us want a big hot dGPU in a big, heavy laptop when all we really need is a better iGPU for casual gaming. My 4800h laptop has no dGPU and works great for most games I play on the go, like tropico or civ, and has the added benefit of working out of the box with linux, unlike dGPU setups. If you are using the iGPU, the higher TDP of the H series chips allows for higher/consistent GPU boosting. The 4800h and4700u are the same chip, but the 4700u only maintains 1200-1300 mhz GPU clocks while the H manages 1600 mhz consistently, the real life result is the H is anywhere from 20-45% faster depending on the title. And when you are not gaming, the H is a stone's throw away from the U in terms of real world battery life.
Granted, I think it would be nice if AMD would make a ryzen 5 with the big iGPU for people like me, but they dont make one, so we have no other choice. A ryzen 5 with the 680m and LPDDR5 RAM would be very interesting indeed.
Even if you are OK with a thicker laptop (I myself miss the days of 0.9-1.0 inch thick laptops with good cooling systems like the dell e6440 or lenovo l440) cooling 75 watts of intel CPU is a loud and difficult affair. That's just too much for a laptop's cooling system, especially if paired with a dGPU.
